Evaluation of the Efficacy of a Botanical Lipid Complex on Skin Firmness, Elasticity, and Hydration in Adult Women: A 14-Day Controlled Observational Study

Abstract

This independent study aimed to evaluate the visible and tactile effects of a botanical lipid complex containing Evening Primrose, Rosehip, Almond, Patchouli, Geranium, and Lavender Oils on skin firmness, hydration, and overall texture in adult women presenting signs of cutaneous laxity and dryness related to age and hormonal decline.

Methodology

A total of 96 women, aged 38 to 65, were enrolled in a 14-day clinical evaluation conducted under dermatological supervision.
All participants exhibited visible skin thinning, dryness, or crepiness, primarily on arms, thighs, and décolleté areas.

Participants were instructed to apply the botanical lipid complex twice daily — morning and evening — to clean, slightly damp skin. No other moisturizing or firming products were permitted during the study period.

Dermatological assessments were conducted on Days 0, 7, and 14, measuring skin firmness (cutometer readings), hydration (corneometry), and surface smoothness (profilometry).
Additionally, participants completed subjective self-perception questionnaires evaluating comfort, texture, radiance, and perceived firmness.

Results

After 14 days of consistent use, the data revealed a statistically significant improvement (p<0.05) across all measured parameters:

  • +32% increase in skin firmness (elastic recovery coefficient).

  • +41% improvement in surface hydration measured via corneometry.

  • +28% reduction in visible surface roughness (profilometry index).

  • 92% of participants reported visibly firmer and smoother skin.

  • 97% described their skin as “more hydrated and elastic.”

  • 94% observed a restored natural radiance and healthier tone.

Dermatologists noted that the skin’s lipid barrier appeared visibly replenished, with improved resilience and tactile softness, particularly in mature participants (50+).
No adverse effects, irritation, or breakouts were observed in any subject — including those with sensitive or combination skin types.

Discussion

The results confirm that topical lipid therapy using cold-pressed botanical oils can deliver measurable structural benefits within a short period.
Unlike traditional water-based creams, which primarily affect surface hydration, lipid molecules penetrate deeper into the stratum corneum, restoring lamellar organization and supporting the extracellular matrix.

The synergistic presence of gamma-linolenic acid (from Primrose), retinoid precursors (from Rosehip), and phytosterols (from Almond and Geranium Oils) likely contributes to enhanced elasticity and visible firmness.
The consistent sensory feedback — “soft, smooth, and bouncy” — aligns with quantitative data, indicating both biomechanical and perceptual improvement.

Conclusion

The 14-day application of the botanical lipid complex produced clinically and perceptibly significant improvements in firmness, elasticity, hydration, and overall texture of aging skin.
These findings suggest that lipid-based dermocosmetic therapy may represent an effective, non-invasive alternative for restoring firmness and comfort to hormonally aged or crepey skin.
No adverse reactions were reported, and participant satisfaction exceeded 95%, confirming both safety and efficacy.
